Product Type: Low HP Sequence Board
Series: Mark IV

Functional Description

DS3800HSQD1J is a Low HP Sequence Board developed by GE. It is a part of Mark IV control system. Responsible for managing the precise execution of startup, shutdown, and operational sequences to ensure safety and efficiency. It automates critical processes such as fuel regulation, synchronization with the power grid, and protection against abnormal conditions like overtemperature or pressure fluctuations. Typically integrated with PLC modules, relay logic circuits, and communication interfaces, the sequence board enables seamless turbine operation while minimizing human intervention. By ensuring that all actions occur in the correct order, it enhances reliability, prevents system failures, and optimizes turbine performance for stable power generation.

Features

• Startup and Shutdown Sequencing: Controls the step-by-step startup process, ensuring proper ignition, acceleration, and synchronization of the turbine with the grid. Manages controlled shutdowns to prevent sudden failures or damage to the turbine components.
• Safety and Protection: Monitors critical parameters such as temperature, pressure, and speed to ensure the turbine operates within safe limits. Triggers alarms or emergency shutdowns (ESD) in case of abnormal conditions, preventing potential hazards.
  Fuel and Combustion Control: Regulates the fuel supply to maintain optimal combustion efficiency. Adjusts parameters dynamically based on load demand and environmental conditions.
  Synchronization and Load Management: Ensures smooth integration of the turbine with the power grid by synchronizing voltage, frequency, and phase. Manages load adjustments to balance power generation and system demand.
• Fault Detection and Protection: Detecting irregularities or failures in turbine operation and initiating appropriate shutdown or corrective measures to prevent damage.
  Communication with Other Control Boards: Acting as an interface between different control modules within the Mark IV system, ensuring seamless information flow and synchronized operation.

Components

• Relay Logic Circuits or PLC Modules – Process signals and execute predefined sequences.
• Input/Output (I/O) Interfaces – Connect with sensors, actuators, and control elements.
• Microcontrollers or Embedded Systems – Execute programmed logic for precise turbine control.
• Communication Interfaces (Modbus, Profibus, Ethernet, etc.) – Enable data exchange with the central control system.
